Aiming at optimizing the energy consumption of HVAC, an conservation optimization method was proposed for HVAC systems based on sensitivity analysis (SA), named combination (SAC). Based SA, neural network and related settings about systems, such as cooling water temperature, chilled temperature supply air were optimized. Moreover, data existing system, various optimal control methods tested eva...

• Annual thermal performance of PTES in Dronninglund, Denmark monitored and analyzed. Trnsys model the developed validated against measurement 2015. The annual charged discharged energy were predicted with a deviation < ±4%. Ratio heat loss from cover, sides bottom respectively 60%, 38%, 2%. Influence soil types diffuser positions on investigated. Water pit storage is an effective long-term sto...

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...
